In your customer menu there is a convergence adjustment feature. just follow the instructions on how to do it. It's pretty simple. But if that doesn't do it, then you may have some components shorted or open in the convergence circuit. If so, then you will need a qualified tech to repair it.

I'm not entirely sure, but I think the problem lies in your Convergence OSD PWB. I had to disconnect mine in the attempt to troubleshoot a problem with my TV and the same thing occurred. I would check your connection from your Convergence PWB to your Convergence OSD PWB; especially if you recently recently changed your IC's to fix a color convergence problem. If that checks out ok I would look for possible problems on the Convergence OSD PWB. Good luck!

Check for closed captioning. make sure it's set to off.

Try and see if there is some sort of a reset feature in the menu. Also try to unplug the set from the wall outlet for a few minutes then plug it back in. That resets the microprocessor from being stuck in a loop of some kind.

When the internal temperature gets high then the photo coupler efficiency decreases. This would sometimes result in the menu display freezing up not being able to see any of the PTV functions. Are you a technician?

Press the "Menu" button on the remote to reveal the on screen menu, then press the cursor up or down until the option labeled "Features" is highlighted. Once the features menu is highlighted, press the cursor up or down buttons until the phrase ''Smartlock'' is highlighted. Next, press the cursor right button until it shows the phrase ''access code;'' on the access code screen, press 0, 7, 1 and 1 again. When the phrase ''incorrect code'' appears, enter a ''new code'' by selecting a four number code of your choice; this code will be used to control all functions related to the Smartlock code feature.
hope this helps

Thanks C-dog., but the problem still exist eventhough i put my closed caption in off mode.
i think i press something in my remote thats why im having this problem because before this problem exixted i even adjusted my color settings and tried the POP, SPLIT, FREEZE and some other buttons...and then i just noticed that everytime i press a button like menu, input...the pop-up onscreen display is all black and can't read the text....
Can you help me with this...many thanks
hi c-dog. i can't find a reset feature in the menu the only reset button i can find is the reset button on picture adjust section. i tried unpluging the wall outlet but still the problem exist, actually i can only view the menus while im turning off the lights and trying to sit very close on the tv, that way i can see a little shadows of the words, basically a black pop-up onscreen on display still showing when pressing any feature button on the remote.
sorry im not a technician.
by the way, on the black pop-up onscreen display whenever i press the feature buttons, when i stand close to the tv and turn off the lights i could see some shadowing of the words but very very minimal visibility and its so hard to read
i was thinking too that its a convergence problem, because when im turning on the tv there's a green shadowing on the left side, but when you start watching programs you wont see that green shadows.
can you just tell me how to fix that convergence problem, i really dont know how, or do i need a qualified technician to do that, or i can do it too?
